Singapore Airlines (SIA) is looking into allegations of rude crew behaviour made by a passenger on a recent flight from Singapore to Kolkata which was delayed by almost three hours, a media report said here today.

On June 8, Flight SQ516 had experienced technical issues on the ground, resulting in a delay of two hours and 52 minutes.

In a Facebook post, Chandni Doulatramani, who was on the plane, claims that cabin crew were rude to passengers who had asked why the flight was delayed, the Straits Times reported.

In her post, accompanied by a video that has since been widely shared, Doulatramani said that upset passengers, who had already boarded the plane, became more agitated when they were allegedly told to remain in their seats with their seat belts on.

The Singapore daily quoted her as saying, “When we confronted the cabin crew, they had no answers, rudely shut us up, threatened to call the cops to arrest us, and said ‘We are in the same situation as you are, don’t ask us, we don’t know anything’.”

She said, “The airline didn’t let anybody go. We were being treated like prisoners, being asked to sit in our seats and wear our seat belts. They told us if we were going to offload ourselves then we wouldn’t be allowed back in and they would put us on another plane which was two days later and they wouldn’t compensate us for any of it.”

In the video she posted, passengers are seen arguing with airline staff.
